Sieger Spintech Equipments Pvt. Ltd offers Roving End Opener with Variable Unwinding Speed. Sieger Spintech Equipments Pvt. Ltd is an ISO 9001 Company. Roving End Opener with Variable Unwinding Speed has been developed to ensure that no damage occurs to the bobbin surface and the fibres are also safely opened during the process. Rovings are removed by applying rotary movement to the bobbins and simultaneously evacuating the rovings. The evacuated rovings are thoroughly opened by applying compressed air current as a medium. This ensures that there is no physical damage to the fibre and bobbin as well. The roving can be effectively used as fresh raw material without affecting yarn quality.
